Abstract

The invention concerns a transition body arranged between a lower section and an upper section of a tower for a wind energy plant. The lower tower section is constructed from several corner posts configured as hollow profiles and the upper tower section is configured in the form of a tubular tower which is essentially round in cross section, with a bottom and a connection flange disposed above the bottom for connecting the upper tower section. The bottom and the flange connect the upper tower section and are joined together by at least one metal casing sheet. The connection of the bottom to the at least one metal casing sheet is a welded construction. A number of connection areas is provided on the underside of its bottom, corresponding to the number of corner posts of the lower tower section.
